First-degree exposure: daily contact with dogs, cats and other animals that do not bite or break the skin. In the case of daily contact without broken skin or bite wounds, rabies vaccination is not required. 2. Secondary exposure or tertiary exposure: secondary exposure refers to being scratched by pets without breaking the skin, and tertiary exposure refers to being scratched or bitten by pets with bleeding or broken skin. Rabies vaccine is required for secondary or tertiary exposure, and rabies immunoglobulin is required for tertiary exposure.
